Blend Mode Mapping

Following are the mapping from OpenGLES blend mode to NXP-RT supported blend modes. 
 

VG Image blend mode mapping (VGLite API 3.x, available only in BSP version 25.06): 

1. OPENVG_BLEND_SRC_OVER : sF=SourceAlpha, dF=InverseSourceAlpha, sAF=One, dAF=InverseSourceAlpha 
2.  OPENVG_BLEND_DST_OVER : sF=InverseDestAlpha, dF=One, sAF=InverseDestAlpha, dAF=One
3. OPENVG_BLEND_SRC_IN   : sF=DestAlpha, dF=Zero, sAF=DestAlpha, dAF=Zero
4. OPENVG_BLEND_DST_IN   : sF=Zero, dF=SourceAlpha, sAF=Zero, dAF=SourceAlpha
5. OPENVG_BLEND_MULTIPLY : sF=DestColor, dF=Zero, sAF=DestAlpha, dAF=Zero
6. OPENVG_BLEND_SCREEN   : sF=One, dF=InverseSourceColor, sAF=One, dAF=InverseSourceColor
7. OPENVG_BLEND_ADDITIVE : sF=One, dF=One, sAF=One, dAF=One 

VG Image blend mode mapping (VGLite API 2.x, available only in BSP version 2.16): 

1. VG_LITE_BLEND_NONE : sAF=One, dAF=Zero
2. VG_LITE_BLEND_DST_IN : sAF=Zero, dAF=SourceAlpha
3. VG_LITE_BLEND_SRC_OVER : sAF=One, dAF=InverseSourceAlpha
4. VG_LITE_BLEND_SRC_IN : sAF=DestAlpha, dAF=Zero
5. VG_LITE_BLEND_DST_OVER : sAF=InverseDestAlpha, dAF=One
6. VG_LITE_BLEND_MULTIPLY : sF=DestColor, dF=Zero, sAF=One, dAF=InverseSourceAlpha
